Which equation have no solution ? Select all that apply
Answer:
7
Step-by-step explanation:
first put them in order
5,6,6,8,9,9
now the ones that are in the middle are 6 and 8 so we find the average by adding them then dividing by 2
6+8=14/2=7
Area of sector = (1/2) * r^2 * α where α = the angle in radians
= 1/2 * 12^2 * π/3
= 72 π / 3 = 24 π Answer
Answer:
Step-by-step explanation:
Your first step will be to set up the problem:
f(x) - g(x)
Next you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8
Hope this helped!
